Glee, when you saw the CPU fan spin then stop then spin, did any of
the other fans do the same thing, or did they keep running steadily?

My video card fan and the case cooling air exhaust fan keep running,
even when the CPU fan is skipping in and out. I think they are all
powered from the same power supply output, so if the power supply was
erratic it should affect all the fans together.

I can't figure this one out. I'll keep working with it and hope for
the best.

Thanks, Bryan, I'll try this as soon as I've completed some other
"explorations." I'm still trying to understand why this power
supply/CPU fan/beeping thing happens only when I first boot this
computer in the morning, or after it has been shut down for a few
hours. This must be some king of thermal problem.

Once I've tried to boot and got the sporadic fan and beeping, then
shut down, all the way, not just re-boot, then the computer will boot
up and everything runs normally. I can then use this computer for
several hours and the problem doesn't show up at all...until I've shut
it down and let it cool off for a few hours.

I'm also wondering if perhaps this could be caused a BIOS setting
error of some sort. The CPU fan may have some settings that let it
spin at different rates under different temperature conditions, and
when everything is thoroughly cooled down this BIOS setting may not
handle things properly.

Could this fan interruption be caused by a faulty fan speed control
module on the motherboard? The BIOS provides means for setting the
fan's on and off temperature values and also for regulating the fan's
speed. Maybe the module that controls this is failing. I'm wondering
if it might shed some light on this if I would plug the CPU fan into a
different fan power socket on the motherboard. Gordon

Brian, I'm surprised to find that this double click left mouse
start-up is so unusual. I've used it in other computers, and like it.
This lets me keep the keyboard dead and inactive when the computer is
shut down and not inadvertently bump some key that starts the
computer.

I checked this out carefully, this morning when I started this
computer after it had been shut down over night. A double click on the
left mouse button brought it alive. I know the computer had been shut
down all the way, and not in hibernate or sleep mode. In fact, I had
pulled the power cable just to be sure it wouldn't somehow try to come
alive during the night and really mess things up.

I just came across the following site and now I'm wondering if maybe
all my recent spate of problems might have been caused by the NVIDIA
Drivers. Do any of you have any further insights into this.

http://blogs.zdnet.com/hardware/?p=7551

Here's the opening clip from this site in case you don't have time to
visit it and read the full text.

I�m getting a steady stream of reports in from NVIDIA users that the
latest 196.75 drivers can cause severe cooling problems, even possibly
resulting in the death of the hardware.

The problem seems to be related to the fan controller, causing the
fans to slow down, and even stop. This happening while the card is in
use is a very bad thing indeed, and can cause poor performance (as the
GPU tries to cool itself down by reducing power) and possibly even
overheat your GPU to the point where the card stops working.

---copy/paste from web site---
NVIDIA 196.75 drivers were released on Marc 2nd, and have now been
removed from the download site. If you are running these drivers it is
HIGHLY RECOMMENDED that you uninstall this driver and immediately
downgrade to the 196.21 drivers.

So, did you roll back the driver? If so, is your problem gone? Enquiring
minds want to know!
